Inherited reloader / New to reloading
I research things to excess before i do anything. So as I was doing my homework, the topic came up with my dad who gave me all of his old reloading gear. Good quality. RCBS single stage press and powder thrower, media tumbler. So i still need: dies, scale, caliper, primer flipper, and a little plastic tray to put them in. I will be reloading .40 S&W to start with and i have a few questions.
1) Die Set. I realize there are people on both of sides of 3pc vs 4pc die sets. My questions is. If i buy the 4 piece. Is the bullet seating die different than the die in the 3 pc? I dont think it is (i think its just in use). Also i will be buying carbide, which eliminates the need to grease the casings so i will not need grease and a pad right?
2) this press (sorry no pics yet) has an arm to put a primer in to press it into the shell. However unless im missing something this means i have to touch the primers which i would like to avoid. Is there something to use this press without touching the primers? I can get a separate hand primer if need be.
3) Case trimming. Does the .40 cal always need to be trimmed or does it not elongate as much as others? If it absolutely needs to be trimmed each time i will need to buy a case trimmer. This is one part of the process that videos and manuals tend to skimp on info about.
4) My dad's old 30-06 shell holder appears to be stuck in the press (and covered in rust). I've been soaking with penetrating grease but I've been afraid to take it off because i dont know if im missing anything. Do these simply slide off (slide off horizontally not lift off vertically). or is there a twist or something i need to do. Any help here is appreciated.
I'm sure i will have more questions to follow but this will do it for now. Thank you all in advance.
